Graphic Method for Design of Eccentric Slider-Crank Mechanism and Analyzing of Feasible Region
Based on the analysis to the geometric relations of eccentric slider-crank mechanism (ESCM) at two limiting positions, a new and simple graphic method for design of ESCM was proposed in the paper. The method has the characteristics of legible concept, concise operation and good practicality. Utilizing the new method, the ESCM could be designed quickly under given conditions (slider stroke H, coefficient of travel speed variation K, the auxiliary conditions such as the length of crank a, length of connecting rod b and deflection distance e) without any calculation. Meanwhile, under given conditions (H, K) the alternative region of crank fixed center A, the possible feasible regions of crank length a and deflection distance e were discussed.
